` BRAKE-HANGER.

i To all whom t may concern.' Y

' Be it known that I, HENRY A. VVAHLERT,

` a citizen of the United States, and a resident `of St. Louis, in the State of'. Missouri, have.

invented a certainnew and useful Improvement in lBrakeeI-Iangers, of which'improvement the following is a specification.l

This invention relates to brake hangers for brake shoes and brake beams, and has for its object to provide an improved form of hanger and connections between the same and the brake head, wherebj7 the distance between the center pin in the hanger andbrake head to the face ofthe wheel tread is reduced to a minimum, and the brake Adesign may readily be applied to a closely connected truck having a minimumA distance between wheel centers. l

In the accompanying drawing: Figure l is a side elevation. partlyT in vertical section,

of a brake hanger and connection embodyingr my improvement; Fig. 2, a rear elevation of the same; Fig. 3, a view similar to Fig. l, but showing a modification; and Fig. 4, a rear elevation of the modification shown in Fig. 3. l

My improvement is particularly adaptedv for use in connection with brake designs wherein the brake beam is pivotally supported at the lower end of the hangeiuwhile the brake head is pivotally connected thereto at an. intermediate point, the brake beams being actuated by a system of truck levers connected therewith. In designs of this' tvpe where the distance between wheel centers is very short, it is very difficult to apply the usual type of hanger and brake head connection, but by using myy improved construction, the design may be readily applied.

According to the construction shown in Figs. 1 and 2. the hanger is made 1n the forni of a channel in cross section. having a web. 4. and flanges, Y5, 5, the channel being deepest. at the pivot point of the brake head where the two side flanges, `-5, are provided with the lpin holes for the brake head pivot pin. 6, the upper end of the hanger being the lower end also being formed with an eye.

8. for a pivotal connection with the end of the brake beam, 9.

. The brake head 1s 'provided with the central projecting rib. 10, of nearly the same thickness as the distance. between the flanges,

For the `purpose of balancingthe brakehead, aba-lanciiig spring, 11,'inay be'mounted on the. pivot pin or bolt, 6, at oneside of the hanger VWhere the bolt is'eXtended through one -o'f the side flanges, 5, 'the-spring being-bent around the bolt and having one end bearing against a. lug, 1 2, projecting fr om the side o the hanger,l and theotherend bearing against a lug, 13, on the brake head.' A shield or cover,.14, lfor protecting the spring` may be mounted on the-bolt, 6, between the vbolt head'and the side of the hanger.

The construction shown in Figs. 3 and -l is substantially the same as that above de'- sciibed except that the brake head is pro- -videdwith two projecting ribsor lianges.

tion where there is plenty of room` for the wide type o f hangers.- IVhen the available space'in this direction is limited, the form of hanger shown in Fig. ljma-y preferably be It will now be seen that I have provided a simple, compact, and durable hanger construction, and one in which the distance between the pivot pin and the face of the wheel tread is reduced to a minimum. The shape of the-hangeralso forms aprotection for the brake' head as it substantially. covers the same and prevents access of dirt `and other foreign matter to the interior of the joint.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

l. The combination of a hanger formed with a single eyesevction at each end and two side members spaced apart and formed interatemeu ocaea'iaia. Application led December 16, 1916. Serial No. 137,282. i

gral with said .eye-sections, a brake head having a projecting rib extending between 4said side members of the hanger', and a pivot piii extending through said side members and said rib.

Q. The combination of a hanger formed with an eye section .at each end and two side .members spaced apart and formed integral with said eye-sections, a4 brake head having a 'l'o'jctin-g' ribei'tending between said side members of the hanger, a p1vot 1 1nexte1`1d ing through said side members and said rib, 'and a balancing sprlng mounted on said into the Space between said anges, anda pivotin extending through said flangesl andri v '4. The Combination of a'lhanger formed Wtha channel ."section vand eye members at its ends, a brake.headA having a projecting rib extending between said' flanges at the deepestI point ofthe channel section, and a pvot pin extending through said flanges and 1ib.

5.` The combination of a hanger formed of two side members spaced apart, a brake head having projecting ribs extending between said members, a pivot pin passing through said members and` ribs, and abalancing springy mounted onsaid pin between the ribs of lt-he brake head.` t

n testimony whereof I have hereunto set my hand.
